UKIRT's Galaxies: A View for the Season
When observatories and planetaria get together to share discoveries,
magic will happen. What starts out as many tiny astronomical images with
location coordinates can become an amazing learning tool for astronomers
and the public.
The United Kingdom Infrared Telescope (UKIRT) on Mauna Kea in Hawai`i
is currently engaged in the most ambitious infrared sky survey ever undertaken,
the UKIRT Infrared Deep Sky Survey (UKIDSS). For
the past three years UKIRT has been systematically scanning the heavens for five different
"colours" of faint infrared light. This survey is scheduled to continue
for another four years.
As part of this survey, UKIRT is looking for very far away faint galaxies.
The expansion of the Universe stretches visible light from the most distant
(and youngest) galaxies and quasars into the infrared part of the spectrum,
and by observing this infrared light we can trace the evolution of
galaxies from their youngest members.
To share these results with the scientific community and the public, the
UKIRT astronomers have been working with the planetarium at the `Imiloa
Astronomy Center in Hilo, Hawai`i, to display them in 3-D. This planetarium
offers the world's first full-dome 3-D stereoscopic presentation of astronomical
data, which presents a powerful tool to visualize and share discoveries.
The image below shows data from the UKIDSS Ultra-Deep Survey (UDS) displayed
on `Imiloa's planetarium dome. The cosmic background radiation is
displayed behind it. This data has to date generated almost 60,000
distance measurements for
these far-away galaxies. As the UKIDSS survey continues, more data will be
added. The long pencil beam in the picture shows the galaxies
at their relative distances in this field. Given the 3-D nature of the data,
the planetarium's software allows us to fly along and through this field of
galaxies. Flying "back home" through these tens of thousands of galaxies
is a beautiful experience, and it gives us a measure of how much there is to
be explored in our Universe.

Light Year
One light year is about 10 million million kilometres or 6 million million miles.
Infrared Light
Infrared wavelengths are longer wavelengths than light waves. They are
typically measured in microns, also called micrometres. One micron is one
millionth of a metre, one 10000th of a centimetre, or one 25000th of an inch.
UKIRT
The world's largest telescope dedicated solely to infrared astronomy,
the 3.8-metre (12.5-foot) UK Infrared Telescope (UKIRT) is sited near
the summit of Mauna Kea, Hawaii, at an altitude of 4194 metres (13760
feet) above sea level. It is operated by the Joint Astronomy Centre in
Hilo, Hawaii, on behalf of the UK Science and Technology Facilities
Council. UKIRT's technical innovation and privileged position on the
high, dry Mauna Kea site have placed it at the forefront of infrared
astronomy since its opening in 1979. UKIRT is currently engaged in a
world-leading infrared sky survey as well as the type of innovative
individual programmes described in this press release. More about the
UK Infrared Telescope:

Science and Technology Facilities Council
The Science and Technology Facilities Council is an independent,
non-departmental public body of the Office of Science and Innovation
which itself is part of the Department of Innovation, Universities and
Skills. It was formed as a new Research Council on 1 April 2007 through
a merger of the Council for the Central Laboratory of the Research
Councils (CCLRC) and the Particle Physics and Astronomy Research Council
(PPARC) and the transfer of responsibility for nuclear physics from the
Engineering and Physical Sciences Research Council (EPSRC). We are one
of seven national research councils in the UK. The Science and
Technology Facilities Council is government funded and provides research
grants and studentships to scientists in British universities, gives
researchers access to world-class facilities and funds the UK membership
of international bodies such as the European Organisation for Nuclear
Research, CERN, the European Space Agency and the European Southern
Observatory. It also contributes money for the UK telescopes overseas
on La Palma, Hawaii, Australia and in Chile, the UK Astronomy Technology
Centre at the Royal Observatory, Edinburgh and the MERLIN/VLBI National
Facility.
`Imiloa Astronomy Center of Hawai`i
`Imiloa Astronomy Center of Hawai`i tells dual stories of the renowned
Maunakea volcano, with its world-famous astronomy and rich traditions of
Hawaiian culture. `Imiloa, which means "exploring new knowledge," reflects
both the Hawaiian voyages of discovery and the explorations of astronomy.
Located on a nine-acre campus above the University of Hawai`i-Hilo, with
spectacular views of Hilo Bay, `Imiloa Astronomy Center provides a unique
experience for visitors, students, and families seeking to explore the
connections between Hawaiian cultural traditions and the science of astronomy.
Framed by a rich Polynesian tradition of exploration,`Imiloa is Hawai`i's
premier facility for interpreting the deepest mysteries of the Universe,
being unraveled by the Maunakea observatories -- the world's largest and
most important collection of telescopes. `Imiloa inspires and educates,
helping us to connect with our origins while we reach for the stars.
`Imiloa features interactive exhibits, planetarium shows, group tours, a
wonderful store, a cafe, and a full schedule of events.
